江苏省农村人口与农村居民点时空变化及耦合关系

Analysis on Spatio-temporal Variation and Coupling Relationship of Rural Population and Rural Residential Land in Jiangsu Province

基于2009-2016年的农村人口和土地利用数据,探讨了江苏省农村人口和农村居民点用地的时空变化趋势,并构建协调度评价模型分析两者之间的耦合关系.研究结果表明:2009-2016年江苏省农村人口数量持续减少,年均减少率为3%,由3429.68万人减少到2581.95万人;2009-2016年江苏省农村居民点用地面积持续增长,年均增长率为0.3%,由102.77万hm^2增长到105.28万hm^2;2009-2016年江苏省农村人口数量与农村居民点用地面积耦合关系失调,土地利用效率低下.

Based on the rural population and land use data of Jiangsu Province from 2009 to 2016, this paper analyzes the spatial and temporal trends of rural population and rural residential land use, and constructs a coordination degree evaluation model to judge the coupling relationship between rural population and rural residential land in Jiangsu Province. The research shows that: In 2009-2016, the number of rural population in jiangsu province continued to decrease with an average annual rate of 3%, from 34.2968 million to 25.819,500;The area of rural residential land in Jiangsu province continued to grow, with an average annual growth rate of 0.3%, increasing from 1,027,700 h m^2 to 1,052,800 h m^2;The coupling relationship between rural residential land and rural population was unbalanced development in Jiangsu Province.
